Question

Many ocean-dwelling animals can use sound waves to communicate with other animals and locate food and obstacles over longer distances than can land-dwelling animals. How is this possible?
a). Sound waves travel faster in air than in water.
b) Ocean-dwelling animals produce louder sound waves.
c). Oceans have less pollution than air does.
d). Sound waves travel farther in water than in ai

Answer 1

D. The reason is because sound waves travel faster in water than in air. Sound is created through vibration. When you think about particles in the air and in water, the particles in the air are further apart making it harder for them to pass the vibration from a sound wave. In liquid particles are closer together, so vibration gets passed along more quickly. 

Answer 2

Many ocean-dwelling animals can navigate and communicate over longer distances than can land-dwelling organisms because sound waves travel farther in water than in air. For example, whales can communicate with each other over thousands of kilometers.
